Plot a Gaussian with a 1/e width of 10 and a center of 50 by entering:
Result = EXP(Expression)
Returns the natural exponential function of the given Expression.
The expression to be evaluated. If Expression is double-precision floating or complex, the result is of the same type. All other types are converted to single-precision floating-point and yield floating-point results. The definition of the exponential function for complex arguments is:
EXP(x) = COMPLEX(eRcos I, eRsin I)
R = real part of x, and I = imaginary part of x. If Expression is an array, the result has the same structure, with each element containing the result for the corresponding element of Expression.
Thread Pool Keywords
This routine is written to make use of IDL’s thread pool, which can increase execution speed on systems with multiple CPUs. The values stored in the !CPU system variable control whether IDL uses the thread pool for a given computation. In addition, you can use the thread pool keywords TPOOL_MAX_ELTS, TPOOL_MIN_ELTS, and TPOOL_NOTHREAD to override the defaults established by !CPU for a single invocation of this routine. See Thread Pool Keywords for details.
